Draw a parallelogram with the shorter diagonal measuring 4 feet. The shorter diagonal divides the parallelogram into 2 congruent right triangles. The measure of the short edge of the parallelogram is x and the measure of the long edge of the parallelogram is 2x. The measure of the smallest angle of the right triangles is 4y-6 and the measure of the complementary angle of the triangles (which is also one of the vertex angles of the parallelogram) is 6y+6. What are the values of x and y? (Round any irrational values to the nearest hundredth.)
